Worksheet: Density calculations

1. Write down the density equation:

Make sure to write the equation, substitute in numbers, calculate answer including appropriate unit. Each question is 3 points.

2. If d = 1.2g/cm³
m= 120.3 grams
what is the volume?

------------------------------------------------------------------------------------------------------------
3. If d = 5.4 g/cm³
m = 23.7 g
what is the volume?

------------------------------------------------------------------------------------------------------------
4. If d = 9.2 g/cm³
v = 42.5cm³
what is the mass?
------------------------------------------------------------------------------------------------------------
5. If d = .4g/cm³
v = .30 cm³
what is the mass?
------------------------------------------------------------------------------------------------------------
6. If d = 5.6g/cm³
m= 11.9 grams
what is the volume?

7. If v = 82.8cm³
m= 120.3 grams
what is the density?
------------------------------------------------------------------------------------------------------------
8. If d = 1.2g/cm³
m= 120.3 grams
what is the volume?
------------------------------------------------------------------------------------------------------------
9. If d = 5.2g/cm³
v= 90.1cm³
what is the mass?
------------------------------------------------------------------------------------------------------------
10. If d = 3.0g/cm³
m= 44.4 grams
what is the volume?

11. A mineral has a density of 3.4 g/cm^3.Using the displacement method to find the volume, the volume of the water (alone) before the mineral was placed in the graduated cylinder was 10 cm³and the volume of the water and the mineral together was 19.7 cm^3,what is the mass of the sample? Would this mineral float or sink if it was added to water?

12. An empty graduated cylinder has a mass of 21.4grams. A liquid is added and the mass of the grad.cylinder and the liquid is 36.3g. The volume is then read to be 16.5cm³. What is the density of the liquid? Would this liquid float or sink if it was added to water?
